application filed January 4, 1915. Serial No. 420.

To all whom it may concern Be it known that I, JAMEs A. WILLIAMS, a citizen of the United States, and resident of Roxbury, county of Sufiolk, State of Massachusetts, have invented an Improvement in Ventilating and Cooling Apparatus, of which the following description, 1n-

connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention relates to improvements in ventilating, cooling and humidifying apparatus and the object thereof is to provide a simple apparatus, cheaply constructed, adapted for use in theaters, restaurants and the household, which will eflectively circulate, cool, and humidif'y the atmosphere at a small expense of installation and a minimum cost in maintenance.

In the usual method of ventilating and cooling rooms a circulation of the air is maintained by one or more electric fans, but such fans merely serve to agitate the air and dust and to give temporary relief as the blast of air is passing. I

The object of the invention is to provide means-for cooling the air which will so distribute the same to the room as to avoid the injurious effects of direct blasts or drafts of air usually caused by electric fans.

Other objects of the invention will more fully appear from the following description and accompanying drawings and w ll be pointed out in the annexed claims.

In the drawings: Figure 1 is a vertical longitudinal'sectional View of one of the preferred forms of apparatus embodying my invention showing in elevation an electric fan for producing the air current,

Fig. 2 is a vertical transverse section on lines 2.2 Fig. 1, and,

Fig. 3 is a horizontal section of one of the air distributing mechanisms on lines 33 Fig. 2. I

The preferred embodiment of the invention as illustrated in the drawing comprises a preferably rectangular ice receiving chamher 1 having a cylindrical aperture 2 1n which is fitted a cylindrical inlet pipe 3 having a flaring mouth 4 adapted to receive the blades of the usual electric fan which has an electric motor 5 secured directly to the shaft 7 of the fan and is supported upon a suitable base or stand 8. The opposite end of the chamber 1 may be entirely conveniently applied to the end of the chamher, or a series of pipes may lead from this end to various parts of the room to be cooled. The tubular discharge pipe as illustrated herein is provided with a series of. angularly disposed vanes 10 radiating outwardly from the vertical axial plane of the pipe and so arranged as to distribute the air which is passed through the ice receiving chamber to various portions of the room, at the same time modifying the blast so that it will not cause injurious effects to the-people within the room.

The ice receiving chamber, which is generally rectangular in form, is provided with a sloping bottom 11 adapted to direct the dripping water from the melting ice to a suitable outlet faucet 12, which may be connected to a discharge pipe 13, leading from the same to the sewer.'

It will however be understood that if de sired the faucet 12 will be provided with a the casing of the ice receiving chamber and which may desirably rest upon a ledge 18 extending around the upper portion of the v ice receiving chamber.

In order to provide for easily filling the -ice receiving chamber the top may be provided with a cover 19 which may be removed to permit free access to the entire upper portion of the chamber, or if desired one of the side walls of the chamber may be made in the form of a door which can be swung aside to permit the ice receptacle to be inserted, in such case the frame 17 beingslid along the flanges 18 until the receptacle is in its proper place.

One of the main objects of the invention is to provide for the passing of the current of air directly over and in contact with the ice in the ice receptacle and it is desirable that the its shall be in the form of large cakes such as are 'commonl manufactured.

I By using cakes of this ciaracter the ice melts with sufi'icient rapidity to maintain the atmosphere in cooled condition without an unnecessary waste of ice, furthermore such 4 pieces of ice are much more easily handled than smaller pieces. i

In Fig. 2 I have illustrated the ice receptacle as being in the form of a deep basket adapted to contain large pieces of ice of this character.

In some instances however as in moving picture theaters where it 1s desirable to have the a1r cooled more rapidly a receptacle may be made of a series of ice receiving compartments such as is illustrate in Fig. 1 in which the receptacle compris s three superposed wire baskets 20, 21, 22 all connected to vertical supports 16 which depend from a frame 17 supported upon the flange 18. In such case the large pieces of ice may lie placed in the lower compartment and smaller pieces in the superposed compartments. When the blast of the fan is blowing over the ice thus arranged the water will drip from the melting ice in each of the upper compartments upon the ice in those beneath, causing a somewhat more rapid melting. At the same time the blast of air will be purified as it passes through the shower of falling water, thus removing dust, germs and other harmful materials from the air? 4 By the apparatus thus far described the air from an ordinary electric fan is cooled andpurified and delivered directly into the room from the outlet of theice receiving chamber. This form of apparatus may conveniently be arran ed at the intake of air into the room so t at pure airmay be inhave the cooling apparatus all within the troduced into the room through the cooling apparatus. I I I In someinstances it may be desirable to room and in such instances additional apertures 24 may be added to the device by providing openings leading outward from the sides of the ice receivmgchamber casing adjacent to the discharge end of the chamher and doors 25 provided for closing said 'apertures when desired. As illustrated herein the doors 25 are supported in sliding brackets 26 so that they may slide longitudinally-of the casing. If it is desired to conduct the air to particular parts of the-room suitable pipes 27 may be connected to or adjacent to the discharge end of the apparatus for such purpose. Such pipes may be provided with branches or extensions leadea ers ing to the portions of the room aforesaid or to separate rooms, telephone booths, etc.

While the apparatus above described is the best form now known to me it is also to be understood that various other embodiments of the invention may be made within the spirit of my invention as set forth in the following claims.

The preferred form of apparatus illustrated in the drawing is so constructed that it may be placed in juxtaposition to a usual form of electric fan, thus avoiding the necessity of a specially built apparatus embodying a fan as apart of the construction.

Having thus described my invention,

.what I claim as new and desire to secure by Letters Patent is:

1. A cooling and ventilating apparatus comprising an ice receiving chamber having an inlet aperture the wall of which is adapted to receive and inclose the blades of an electric fan, an ice receptacle removably sup-ported in said ice receiving chamber consisting of a supporting frame having a series of horizontal superposed reticulated ice containers so disposed that a blast of air from a fan through the said ice receiving chamber will impinge directly u on the ice 1n saidco'ntamers and an outlet or said ice receiving chamber located directly opposite said inlet aperture, a plurality of vertical diverging vanes within said outlet for distributing the cooled air throughout the room.

2. A. cooling and ventilating apparatus comprising a rectangular ice receiving chamber havinga circular inlet aperture, 9. flanged conduit leading to said inlet aperture adapted to surround the blades-of an electric fan, said ice receiving chamber having a delivery aperture 7 directly opposite to the inlet aperture and having also lateral apertures, and means for closing the same.-

3. A. cooling and ventilating apparatus comprising a rectangular ice receiving chamber having at one end a circular inlet aperture, a flanged conduit leading to said. inlet aperture adapted to surround the blades of an electric fan, a circular delivery aperture in the opposite end of said chambcr'directly opposite to said inlet aperture and supplemental apertures adjacent to said
